FILLER COMPOUNDFOR TIRES.

SPECIFICATION forming part of Letters Patent No. 698,454, dated April 29, 1902.

Application filed November 7, 1901.

T0 wZZ whom) it may concern:

Be it known that I, ADOLFODE CLAIRMONT, a citizen. of the United States, residing at T0- peka, in the county of Shawnee and State of Kansas, have invented certain new and use ful Improvements in Filler Composition for Tires; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

Thisinvention relates to anew composition chiefly designed to prolong the life and. period of usefulness of pneumatic tires and render them invulnerable and punctureproof. In compounding this mixture I use the following ingredients or their substantial equivalents in about the proportions stated, 2'. e.: gl u,e one part; molasses, one part; water, one part; granplated cork one part; resin, one -half part? .The g ue 1s placed in the water and allowed to stand untilsoft, the water being absorbed and the glue swelling and becoming jellied. This gelatinous mass is liquefied in a hot-water bath, after which the molasses is added boiling hot. This mixture is kept about at the boiling-point of water in the bath for thirty minutes, or thereabout, after which the granulated cork is added.

'Gl may be used instead of or in comhim the glue, and the latter may be Serial No. 81,436. (No specimens.)'

erably by being pumped thereim When the composition is cool and sets,which will be in about five to six hours, it will be found firm, elastic, and light.

While the composition is designed most especially for old and worn tires, it may be used as a fillinglfor a casing of any make or character,bein g adaptable forlight and heavy tires alike. A tire filled with the composi tion aforesaid is puncture proof and possesses all the resiliency of a pneumatic tire and is far more serviceable.

The resin may be added at any time; but it is preferred to place it in the boilingmixture of glue and molasses and let it dissolve thoroughly before the addition of the cork or like material.

The composition has been found useful in filling truss-pads, cushions, and like articles.

The resin renders the composition more or less hard or elastic, according to the temperature, in addition to its function as a binder for the cork.

Having thus described the invention,.what is'claimed as newis- .1. A composition of matter for filling tires consisting of glue, molasses, water and granulated cork in about the proportions specified.

2. A compositionof matter for filling tires consisting of glue, molasses, water, resin and granulated cork in about the proportions specified.

In testimony whereof I aifix my signature in presence of two witnesses.
